Do these cups come in a box or are they separate?

These cups are shipped in a box.

What lid fits these cups? I purchased 12ftl white, but they are too small.

The 12J16 item is a 12oz cup with a wider 16oz rim. The most common lid for cold beverages is the 16SL or 16FTLS. The most common lid for hot beverages is the 16EL or 16RCL. The full list of compatible lids includes the following: 16SL, 16JL, 16UL, 16FTL, 16FTLS, 16EL, 16ELBLK, 16RCL, 16RCLBLK, 16LCD, 16LCDH, and 16LCDHX.

are these cups safe to use in the microwave since they are made out of foam?

No way. Studies show that styrene, a likely carcinogen, can leach from polystyrene foam cups and containers when heated. Never put hot food/drink into polystyrene foam containers, and never microwave these (or any plastic) products. When you ingest hot liquids and possibly hot food from polystyrene foam cups and plates is that the styrene may leach out of the foam food service ware and into our bodies. Plain words causes Cancer..

Do these come with lids?

No. I found lids on Amazon that stated they fit 20 oz cups and they work fine. I think it was a 500 pack of lids.
